United Launch Alliance

United Launch Alliance, LLC (ULA) is an American launch service provider formed in December 2006 as a joint venture between Lockheed Martin Space and Boeing Defense, Space & Security. The company designs, assembles, sells and launches rockets. The company uses rocket engines, solid rocket boosters, and other components supplied by other companies. When founded, the company inherited the Atlas V rocket from Lockheed Martin and the Delta rocket family from Boeing. As of 2024, the Delta family has been retired and the Atlas V is in the process of being retired. ULA began development of the Vulcan Centaur in 2014 as replacement for both the Atlas and Delta rocket families. The Vulcan Centaur completed its maiden flight in January 2024. The primary customers of ULA are the Department of Defense (DoD) and NASA, but it also serves commercial clients.
